Bear in mind, Yuri, that most of us don't have access to multiple welding aparatuses and all the cool tools you have in the Batcave.

Right...so a few of my entries may be tailored to those of us with access to a bigger shop. However, some projects are far easier. Take, for example, the stir plate - for less than a $60 investment (and some patience), just about anyone can get all of the tools and parts to make their own.
